COMBINED BUSHING AND VALVE.

Specification of Letters Patent.

Patented Ma 18, 1920.

Application filed July 10, 1918. Serial No. 244,260.

To all whom it may concern Be it known that I, JOHN ALBIN ANDER- SON, a citizen of the United States of America, residing at Lockport, in the county of Will and State of Illinois, have invented new and useful Improvements in Combined Bushings and Valves, of which the following is a specification.

This invention is designed principally to provide a bushing in the form of a conventional pipe bushing in which there is seated a valve, the latter having means for retaining it on its seat, except when a smaller pipe is attached in the bushing whereon the valve is unseated, thereby placing in communication the two parts for which the bushing acts as a connecting means.

Other and further provisions of the invention are made to appear in the following detailed description of the same.

lVhile illustrated and described in a speciiic embodiment, the invention is not to be restricted to such. Continued use in practice may suggest certain desirable changes or alterations and the right is claimed to make any which do not deviate from the scope or the subjoined claims.

In the accompanying drawings:

Figure 1 is a perspective view showing the practical application of the invention.

Fig. 2 is a longitudinal view through the invention.

Fig. 3 is a transverse sectional view on the line 2-2 of Fig. 2.

As illustrated the invention which is in the form of a bushing is shown as attached to an oil barrel 1 in the head 2 thereof; so that a pipe or cock may be readily attached to the barrel. to draw off the latters contents. The improved bushing comprises a body 3 with the hexagonal shouldered end 4: by means of which it may be turned with a wrench. This body 3 is threaded internally and externally, the external threads engaging threads in the head 2 of the barrel 1 while the internal threads of the body are intended to receive the external threads of a pipe or cook, not shown. So far as the body itself is concerned, the bushing simulates the conventional pipe bushing or re ducing nipple. f

At that end opposite the shouldered portion 4, the body is formed with a valve seat 6, so that the valve 7 may seat thereon, the valve itself being of the disk type and provided with a stem 8. Disposed transversely across the body of the bushing and adjacent to the valve seat 6 there is a transverse member or web 9 which is relatively narrow so that it may not obstruct the body at the valve end of the latter. This web 9 has formed therein a hole centrally positioned both with respect to the length and width of the web and the valve stem 8 passes loosely through this hole, in order that 1on gitudinal movement imparted to the stem may serve to seat or unseat the valve, depending on the direction in which the stem is moved.

The stem 8 extends through the bodytoward the shouldered end of the latter and near its free end is formed with a transverse member or guide 10, the latter being of sufficient length to permit its ends to slidingly engage in longitudinal recesses 11 cut in the interior wall of the body and at diametrically opposite sides of the latter. This guide or transverse member 10 serves to preclude any angular movement of the valve but its sliding engagement with the recesses 11 permits longitudinal movement of the stem to seat or unseat the valve.

In order that the valve may be held normally seated, a spiral spring 12 is compressed between the web 9 and the guide 10 and is positioned so as to be in surrounding relation to the stem 8.

It is obvious from the construction dis closed that the attachment of the body to the head of the barrel 1 will serve as a means for attachment of a pipe or cook to the barrel but this means will be closed, it the valve 7 is allowed to seat and it will be allowed to seat as long as no pressure is exerted on the guide 10 on that face opposite .nat against which the spring 12 presses. When a pipe or cock is screwed into the body 3, its end will bear on the guide 10 and continued screwing of the said pipe into the body will thus operate to unseat the valve.

as a result of the pressure exerted upon the guide 10 the unseating of the valve 7 serves to then place the pipe into communication. with the interior of the barrel and will permit the How of a liquid from the barrel into the pipe.

The stem 8 is provided with a threaded extension 5 just above the guide 10-and on this extension there is received a disk 13 having a square hexagonal boss 1a by means of which the disk may be turned to seat the disk on the shouldered end of the body to lock the valve 7 a position of closure, as is apparent. r 7 7 It is obvious that the improved device may be used as a bushing for beer kegs as a means for permitting the ready attachment of spigots; that it may be used as a closure for one pipe for which an extension is attached; and that it is useful in various other instances'for performing the character of service set forth. a v The inventlon having been described what is claimed as new and useful is:

l. A device of the kind described comprising a' hollow cylindrical body threaded both exteriorly and interiorly, the interior wall having longitudinal recesses formed at diametrically opposite points, the body having a valve seat formed at one end and carrying a web positioned transversely thereacross and adjacent to the valveseat, a valve, a valve stem connected with the valve and "passing 'slidingly through the web, a guide carried on the stem at the end remote" from the valve, the guide having its ends in slid- 111g engagement with the 7 said recesses, a

o spring in surrounding relation to the stem and compressed between the guide and the web, the stem being provided with a threaded extension at the end remote from the "valve, and. a disk engaged on said threaded end for axial movement along the stem to engage the cylindrical body on the end and lock the valve in closed position when not-in useL r g 2. A device of the kind described comprising a hollow cylindrical body threaded both exteriorly and interiorly, the interior 1101- low having longitudinal recesses formed at diametrically opposite points, thebody hav- 7 ing a valve seat formed at one end and carry ng a web positioned transversely thereacross and ad acent to the valve seat, a valve JOHN ALBIN ANDERSON.
